■ 質(zhì)粒簡介
pET-3a載體是一個大腸桿菌表達載體，T7啟動子驅(qū)動T7標(biāo)簽和目的基因融合表達。該載體是組成型表達，并且不攜帶6×HIS標(biāo)簽。The pET-3a-d vectors carry an N-terminal T7?Tag sequence and BamH I cloning site. These vectors are the precursors to many pET family vectors; the pET-23a-d(+) series corresponds to pET-3a-d but incorporates several additional features. Unique sites are shown on the circle map. Note that the sequence is numbered by the pBR322 convention, so the T7 expression region is reversed on the circular map. The cloning/expression region of the coding strand transcribed by T7 RNA polymerase is shown below. 質(zhì)粒只保證關(guān)鍵序列正確，不保證表達效果。
